First conversion from virtual machine to virtual machine template needs to call powerOffVMTask (vmRef) and closes virtual machine, then calls markAsTemplate (vmRef) virtual machine and transforms virtual machine template.
Virtual machine template has been preserved according to different types of service, and the virtual machine dissimilar for dynamic load lays the foundation.Meanwhile, system will manage virtual machine template as required, as interpolation, the deletion of virtual machine template, and the unlatching of virtual machine, closedown, establishment, deletion.
Step 2, when user needs the virtual computing node of an increase particular type, can by virtual machine add interface carry out virtual machine interpolation operation.
User can select virtual machine template type, the server ip of needs interpolation, the information such as CPU, internal memory of distribution, then submits this information to.
Then system once can carry out the work that virtual machine dynamic creation and PLATFORMLSF node dynamically add on backstage, specifically describes as follows.
Step 3, virtual machine dynamic creation.
First the API that system can be called VMwarevSphere and provides realizes the clone of virtual machine template to virtual machine, and now VMwarevSphere can dissolve a virtual machine by example in the physical machine be added;
The establishment of virtual machine needs to call cloneVMTask (vmRef, folder, virtual machine name, cloneSpec) and template is deployed as virtual machine, and now the title of virtual machine can be self-defined.
Then system can be modified to the configuration of virtual machine, comprises available CPU, internal memory etc.; After having revised, the API that system can call VMwarevSphere to be provided realizes the startup of virtual machine.
Start-up operation can be carried out to the virtual machine formulated by calling powerOnVMTask (vmRef, null).
By call reconfigVMTask (vmRef, configSpec) can revise virtual machine can CPU, internal memory etc.
The IP of the network interface card of virtual machine can be set by the setAdressType (" generated ") calling VirtualEtherentCard;
Step 4, PLATFORMLSF node dynamically add.
When virtual machine creating completes, system can obtain the IP of this virtual machine, and the API then calling PLATFORMLSF notifies the virtual machine of this IP of PLATFORMLSF dynamic load.The node corresponding with this IP can be searched in point spread pond after PLATFORMLSF receives this information, after finding, the type of this node is set to available, and this node of Dynamic link library.Such PLATFORMLSF node dynamically adds and just completes.
Through said process, a new virtual machine node is just dynamically added and is completed.The calculation task issued afterwards can dynamically be issued to each node according to the load balancing principle of PLATFORMLSF, comprises the new virtual machine node created.
As can be seen from the above description, present invention achieves following technique effect:
1) can dissimilar virtual machine template be managed; 2) can open dynamically, close, create, delete virtual machine; 3) can notify that PLATFORMLSF adds dynamically, delete virtual machine node; 4) technology that have employed a kind of node administration pond realizes the dynamic management of computing node; 5) information of virtual machine, virtual machine template, computing node etc. can be checked easily, and to the conscientious operation of above-mentioned information; 6), after node has dynamically added, calculation task can be automatically assigned on newly-increased node and perform by system.
In a word, by the embodiment of the present invention, improve the autgmentability of group system, availability, operating speed, can realize dynamically assembling group resources of virtual machine kind by the demand of compute type, improve the utilance of system resource.
